DOI: 10.1002/mrm.29222
Abstract: Single‐voxel MRS (SV MRS) requires robust volume localization as well as optimized crusher and phase‐cycling schemes to reduce artifacts arising from signal outside the volume of interest. However, due to local magnetic field gradients (B0… read more here.

DOI: 10.1016/j.jappgeo.2020.104220
Abstract: Abstract In recent years, high-frequency passive surface wave methods based on seismic interferometry have been applied to estimate near-surface shear wave velocity structure in urban geophysical investigations. One of key steps of using surface-wave methods… read more here.

DOI: 10.1049/iet-pel.2017.0689
Abstract: Power electronic converters are consistently encountering complex non-linear behaviours predominantly due to the coupling of electromagnetic interferences (EMIs). The emergence of non-linear phenomena in a DC–AC H-bridge inverter under the influence of periodic interference signals… read more here.
